Control transparency of a top layer provided by an additional transparent layer on top of the top layer based on relevance

ABSTRACT

A method, system, and program product are provided for controlling layers in a graphical user interface. The method includes an operating system function of a mobile computing device running a current application with a current layer of user interaction via the graphical user interface, detecting an event providing a top layer display, determining if the top layer display has sufficient relevance to the user to interrupt the current application. If the top layer display does not have sufficient relevance, the method makes the top layer display control transparent so that the user continues to interact with the current application in the graphical user interface while maintaining the top layer in visual order. When the top layer is control transparent, the method may provide a visual cue of control transparency to the user.

BACKGROUND

The present invention relates to graphical user interfaces, and more specifically, to control of layers in a graphical user interface.

A computing device such as a smart phone or tablet with a touchscreen user interface or a computer system with a non-touchscreen user interface may have multiple layers or windows on the graphical user interface (GUI) that the user may interact with. It is often not possible for the user to access different layers of the GUI due to the top layer taking preference. For example, a top layer may be a pop-up box with an event notification, or an instant messaging chat window, etc.

In one example, an instant messaging chat may be provided as a layer over an open application on a GUI. The user may not be able to access the application behind the area of the instant messaging chat without removing or closing the instant messaging chat. Furthermore, if an event is triggered in the instant messaging chat that creates another layer over the top of the chat, the user may no longer access the chat as a result of its priority.

Additionally, if a user is typing or interacting with an application and a chat appears as a layer on top of the application, the user may interact with the chat by mistake because that layer has preference over the application in which the user was typing leading to errors and frustration by the user.

The user may be forced to interact with a top layer in the area where the top layer obscures the layer below before interacting with the layer below. In some cases the pop-up event notifications do not need an action, but the user must wait for the event notification to end in order to continue interacting with an application on a layer below.

DETAILED DESCRIPTION

Detailed embodiments of the claimed structures and methods are disclosed herein; however, it can be understood that the disclosed embodiments are merely illustrative of the claimed structures and methods that may be embodied in various forms. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of this invention to those skilled in the art. In the description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments.

A computing device may have a graphical user interface having multiple layers of a graphical user interface (GUI) for simultaneously interacting with multiple applications and the operating system. The computing device may be a mobile computing device in the form of, for example, a smartphone, a tablet computer, a personal digital assistant, a smart watch, or another form of device having a touchscreen graphical user interface. The computing device may alternatively be a laptop or desktop computer or other computing device having a non-touchscreen graphical user interface.

The graphical user interface may receive user inputs via a pointer device such as a mouse or keypad, or via touch in the case of a touchscreen. A touchscreen user interface is an input and output device provided with an electronic visual display of a computing device. The user can use the touchscreen to react to what is displayed by making inputs or control the computing device through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.

When interacting with a device, the user may interact with different layers of the GUI. GUI layers or windows are used as a means to separate out various related interface elements to their own groups, for example, as belonging to a specific application. The layers may be thought of as transparent superimposed slides providing GUI controls for a particular group. The use of layers enables entire groups of controls to be turned on or off simultaneously thereby controlling which interface elements the user may interact with.

Referring to FIG. 1, an exploded schematic diagram 100 shows an example embodiment of a mobile computing device 100 with a graphical user interface 120 in the form of a touchscreen user interface. The touchscreen user interface 120 may include layers such as an operating system user interface layer 130 and application user interface layers 140. Each application may user multiple layers if it requires superimposed displays for the application content.

A top user interface layer 150 may be provided that may be an application user interface layer 140 or a layer used by the operating system for alerts, or other forms of prioritized content. The top user interface layer 150 may be used to display 152 information, such as a pop-up notification or alert, and may include one or more control elements 154 for interacting with the display 152.

The top user interface layer 150 may display 152 information provided by a variety of user interface implementations. The top layer display 152 may be controlled by the operating system or middleware in an application operating on the operating system. Top layer displays 152, whatever form they take, have the common property that they require interaction to action them, remove them, or the elapse of a predefined time period before they are no longer displayed on top of a current application and the user can revert to their activity on a current application.

Top layer displays 152 may be due to an always-on-top layer for displaying prioritized content; the prioritized content may be from applications other than the application currently being used and displayed on the user interface. The top layer displays 152 may be alerts from the operating system or from applications that have settings in the operating system enabling alerts to be displayed. The top layer displays 152 may be modal windows of the application currently being used and displayed on the user interface to notify the user of information that is relevant to the application.

The order of layers of a user interface 120 may be described by a depth or z-order in the z-axis of the display plane and a layer class priority may be provided in the operating system and applications for prioritizing touch handling of the user interface layers. Displays of applications currently executing on a mobile device may be rendered in a depth or z-order based on priority determined between the applications.

In one embodiment, multiple layers of the graphical user interface may be provided and may be hardcoded into a GUI layers script. Controls may be placed on a layer by setting a layer field in Extensible Markup Language (XML).

The described method and system determine the relevance of a top layer display to the user and make the top layer control transparent if it is not relevant so that the user may continue to interact with a current application on a lower layer without being interrupted. The user may be made aware of the top layer display, however the control transparency may enable the user to revert to the notification when they are ready. This gives more control to the user with regards to layers, by allowing them to access and control different layers and optimizing when they access these layers.

The layer of the GUI that the user interacts with on the UI is determined based on a relevance of a layer in a given situation. The relevance determination may be made based on past interaction of the user with the given type of top layer notification.

Referring to FIG. 2, a flow diagram 200 illustrates an example embodiment of an aspect of the described method as carried out by an operating system functionality of a computing device.

A current application may be running 201 in a current layer being interacted with by a user of the computing device. An event may occur 202 in an application or the operating system and the application or operating system may provide a top layer display providing information on top of the current user interface layer of the current application.

The application may be a background application running simultaneously with the current application or may be the current application itself. For example, a background application may be an instant messaging application and an event may be the receipt of an incoming message. In another example, the current application may generate events that create modal windows. In a further example, the operating system may generate alerts or notifications relating to its functionality or that of other applications.

The method may determine 203 if the top layer display is in the same area of the screen as currently being used by the user for the interaction with the current application. The method may identify where the user is interacting with the current layer and compare this to where the new top layer display is to be displayed that may potentially block the interaction. For example, an area bounding coordinates where the user has interacted with the graphical in a predefined time period may be compared to the coordinates of the event display in the top layer. If these coordinates overlap, then the top layer display is likely to interfere with the user's current interaction. Alternatively, the method may skip this step and consider any top layer display to be an interruption to the user.

If the top layer display is not in the same area, the method may enable the event display in the top layer with control passed 206 to the top layer of the user interface. This may be implemented as a usual top layer display would be activated.

Whilst control is at the top layer, it may be determined 207 if a defined first graphical user interface input or gesture in the case of a touchscreen is received to dismiss the top layer display and to return 208 controls to the previous current layer of the current application.

The method may determine 204 if the event display is critical. The determination may be based on predefined rules for critical notifications. Critical notifications may be operating system event notifications that affect the operation of the computing device. The predefined rules may be configured by a user to enable event displays from predefined applications or relating to predefined events of certain applications. As an example, a user may configure a rule to allow event displays in the form of an instant messaging chat from a particular person. This may be configured for a certain period of time.

If an event display is determined 204 to be critical, the method may enable the event display in the top layer with control passed 206 to the top layer of the user interface. This may be implemented as a usual top layer display would be activated.

Whilst control is at the top layer, it may be determined 207 if a defined first graphical user interface input is received to dismiss the top layer display and to return 208 controls to the previous current layer of the current application.

If an event display is determined 204 to not be critical, the method may determine 205 if the event display has sufficient relevance to the user for the user to be interrupted from their current activity. The relevance determination may be based on whether the event display has any actionable control items in it and based on learning from past interaction of the user with this type of event display. Further details of the relevance determination are provided with reference to FIG. 3.

If it is determined 205 that the event display has sufficient relevance to interrupt the user, then control is passed 206 to the top layer display. As before, whilst control is at the top layer, it may be determined 207 if a defined first graphical user interface input is received to dismiss the top layer display and to return 208 controls to the previous current layer of the current application.

If it is determined 205 that the event display does not have sufficient relevance to interrupt the user, the event display may be displayed but in a control transparent form 209. Therefore, the graphical user interface control remains with the current application.

The control transparency may be achieved by various methods and systems as described with reference to FIGS. 4A and 4B. In these methods and systems, the top layer control elements are made ineffective by being deactivated, overridden by other controls, or by having their priority changed. This enables the control elements of the current application layer to continue to function.

The event display may be made partially transparent to enable the user to see the control elements of the current application layer. If the event display is fully displayed and not partially transparent, the user may continue interacting with the current application layer by remembering what was behind the top layer event display. For example, a top layer event display may fully or partially cover the keyboard controls of the current application layer in a touchscreen user interface, however a user may continue to type, as they know the order of the keys in the keyboard.

It may be determined 210 if a defined second graphical user interface input or gesture in the case of a touchscreen is received to activate the top layer display to enable control of the event display. For example, in a touchscreen user interface, the user may press and hold the layer on top, which does not have any control, to tell the operating system that the user wants to control that layer. Alternatively, if the operating system detects that the user has not interacted with the current application for a predefined period of time, it may default all controls to the top layer.

If such as user interface input or gesture is received, the method may pass 206 control to the top layer. If such a user input or gesture is not received, the control may stay 211 with the current layer of the current application.

In this way, operating system level function decides layer control for the user based on determined relevance of an event display.

If a top layer is control transparent, it may remain displayed until an input or gesture is received 210 or a timer may be provided after which the event display may be converted to a display symbol or other non-top layer notification.

Referring to FIG. 3, a flow diagram 300 illustrates an example embodiment of an aspect of the described method as carried out by an operating system functionality of a computing device for determining relevance of an event display as required at step 205 of FIG. 2.

The method may start 301 a relevance determination. As an optional consideration, it may be determined 302 if the lop layer event display has any actionable controls. This may be determined by detecting control elements in a top layer display. If there are no actionable controls, then sufficient relevance is not reached 305. In this case, the method may continue as described in FIG. 2 with the top layer display being partially transparent. This may ensure that the event display is seen but that it does not interfere with the current application.

It may be determined 303 if historical interaction of the user with this type of event display is to dismiss it. The historical interaction may be a score determined by past user interactions with this type of event display. For example, it could be determined by how many times the user has interacted with the event display when it has appeared as a top layer, as opposed to dismissing it immediately before performing any actions. It may also depend on how long it takes for a user to dismiss an event display after it appears. Dismissal refers to removing a layer from the screen or closing an application after it pops up, though input or gesture control. Interaction refers to using buttons on the screen, and opening notifications.

A log may be maintained of historical user interactions with event displays on a top layer, which may be used to set the relevance determination. The log may categorize event display types, for example, by application. The log may be continually updated enabling the relevance determination to be improved during ongoing learning from the user's reactions to event displays.

If it is determined 303 that the historical interaction is to dismiss the event display, then sufficient relevance is not reached 305. However, if it is determined 303 that the historical interaction is not to dismiss the event display but instead to interact with it, then sufficient relevance is reached 304. This determination outcome is used in step 205 of the method of FIG. 2.

In this way, an algorithm decides if an event display layer is actionable, and if the layer is not actionable or the user never actions upon it, the controls of the computing device remain on the current layer that was already being operated on. Furthermore, if the layer is actionable, then the user will be able to access the previous layer through gesture control as described in relation to FIG. 2.

In one example embodiment, a user may have a mobile phone running an application and there is a messenger application in the background that is not open or displaying on the screen.

The user receives a message. The messaging application attempts to notify the user about this message by creating a new layer on top of the layer the user is currently acting on. One example is a chat head that allows a user to read and reply to instant messages while using another application.

The described method determines whether it the new layer is actionable by checking if there is anything the user can interact with on the layer, such as buttons.

The described method may also have recorded how the user interacts with this type of new layer in the past, to determine the relevance to the user. For example, if a user never interacts with a messenger new layer and always dismisses it, the method will assign no relevance to it.

If the new layer is more important or relevant than the current layer, the control of the screen moves to the new layer. The previous layer may now be accessed using gesture control, for example, two fingers instead of one finger gesture.

If the previous layer is more important or relevant or the top layer has nothing actionable, the top layer is disabled and control remains on the current layer being used prior to the event.

To ensure that pop-ups that are critical to the operation of an application are not dismissed through this method, a locking state may be imposed for critical layers ensuring these are not dismissed and meaning that the user cannot access previous layers during the popping of critical layers.

Referring to FIGS. 4A and 4B, schematic diagrams 400, 410 are used to describe example implementation of control transparency of a top layer. These implementations may be applied to a computing device having a touchscreen. Equivalent implementations may be applied to a computing device with a non-touchscreen user interface, for example, using a window manager.

A current application layer 440 is provided with example controls 441, 442 at locations on a touchscreen display. A top layer 450 is generated with a display 451 on top of the current application layer 440. The top layer display 451 has an example control 452.

A first embodiment of control transparency is described with reference to FIG. 4A, in which an additional layer 460 that is completely visually transparent is provided on top of the top layer 450 when control transparency of the top layer 450 is required. The additional layer 460 relays all user inputs to the current application layer 440. The additional layer 460 has nothing displayed but has touch control that relays the touch inputs such as those in the control areas 461, 462 corresponding to the controls 441, 442 back to the current application layer 440 overriding any controls 352 in the top layer 450.

A second embodiment of control transparency is described with reference to FIG. 4B, in which all inputs to the top layer 450 are relayed to the current application layer 440 at exactly the same location on the screen where the controls were mapped. Any controls 452 in the top layer 450 are disabled as shown by the dashed outline of the control 452. Touchscreens have an (x,y) coordinate for when the user input is received and this can be inputted to the current application layer 440 behind the top layer 450.

A third embodiment of control transparency may be implemented by changing the operating system's understanding of the order of the layers. Normally, the operating system may equate the visual order of the layers to the control order of the layers. However, these two parameters may be separated changing the order of controls. For example: there may be order 1 2 3 in terms of visual layers, and order 1 3 2 in terms of control layers.

The display 451 of the top layer 450 may be made partially transparent as shown by the dashed outline in FIG. 4A and FIG. 4B enabling the user to see the controls 441, 442 of the current application layer 440 through the display 451.

Alternatively, the display 451 may be fully displayed and may cover the display of the controls 441, 442 in the current application layer 440. The user may continue to interact with the current application layer 440 with the hidden controls 441, 442 as the controls will be active due to transparency of controls in the top layer 450.

The described method focuses on user input and rather than hiding displays, allows them to co-exist but with control transparency so that the user can continue to interact with the previous layer. The method keeps user input at the last most contextually relevant layer in a stack of the device.

The advantage of the described method lies in changing the layer the user controls depending on the relative relevance of a layer in a given situation, and making layers control transparent so that users can control the layers beneath.

The top layer optimization component 520 may include a display altering component 529 for altering the top layer display to make it partially transparent.

The top layer optimization component 520 may include a critical display component 525 for determining if the top layer display is critical, and if it is critical maintaining the user interface control with the top layer display. The critical display component 525 may include a configuring component 526 for enabling configuration of types of top layer displays as being critical.

Referring now to FIG. 6, a schematic of an example of a system 600 which may be a form of a computer system 612 with a graphical user interface on which the described system may be implemented.

The computer system 612 may be operational with numerous other general purpose or special purpose computing system environments or configurations.

System memory 628 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 630 and/or cache memory 632. By way of example only, storage system 634 may be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). As will be further depicted and described below, memory 628 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.

The computer system 612 may include Input/Output (I/O) interfaces 622 for communicating with one or more external devices such as a keyboard, a pointing device, or a graphical display 624. The graphical display 624 may be a touchscreen user interface that enables a user to interact with the computer system 612 via a graphical display 624. The computer system 612 may also communicate with any devices (e.g., network card, modem, etc.) that enable computer system 612 to communicate with one or more other computing devices. Still yet, computer system 612 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 620. As depicted, network adapter 620 communicates with the other components of computer system 612 via bus 618.

The communication element 650 may include a subscriber identity module (SIM) in the form of an integrated circuit that stores an international mobile subscriber identity and the related key used to identify and authenticate a subscriber using the communication device. One or more subscriber identity modules may be removable from the communication device or embedded in the communication device.

The communication device may further include a contactless element 660, which is typically implemented in the form of a semiconductor chip (or other data storage element) with an associated wireless transfer element, such as an antenna. The contactless element 660 may be associated with (e.g., embedded within) the communication device and data or control instructions transmitted via a cellular network may be applied to the contactless element 660 by means of a contactless element interface (not shown). The contactless element interface may function to permit the exchange of data and/or control instructions between mobile device circuitry (and hence the cellular network) and the contactless element 660.

The contactless element 660 may be capable of transferring and receiving data using a near field communications (NFC) capability (or near field communications medium) typically in accordance with a standardized protocol or data transfer mechanism (e.g., ISO 14443/NFC). Near field communications capability is a short-range communications capability, such as radio-frequency identification (RFID), Bluetooth, infra-red, or other data transfer capability that can be used to exchange data between the communication device Y00 and an interrogation device. Thus, the communication device may be capable of communicating and transferring data and/or control instructions via both a cellular network and near field communications capability.

The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
